Notable as an early effort from renowned horror filmmaker Wes Craven, this made-for-TV occult thriller was loosely adapted from a novel by Lois Duncan. Star Linda Blair -- whose film career had taken a detour into TV-movie territory after her legendary bow in
The Exorcist
-- returns to the demon-possession genre as a teenager who can't seem to convince her parents that her visiting southern-belle cousin (Lee Purcell) is an evil witch. Purcell's diabolical meddling seems focused entirely on the innocent Blair, who loses both her prize horse and her boyfriend to the scheming sorceress before the rest of the family catches on. Though Craven's well-known extremism is curbed by the limitations of television, his talent at generating high-intensity suspense is still evident, making this a modestly entertaining horror item.
